Description
Abstract
We have performed a karyometric study of
the pyramidal neurons of CA1 and CA3 fields of the
Ammon's horn, in male mice aged from the 5th to the
190th postnatal day. Nuclear sizes were measured with
the aid of a Magiscan Analysis System, used in an
interactive form, in both superficial and deep layers of
the stratum pyramidal in those fields. The measurements
were made at three different topographic levels: rostral;
intermediate; and caudal, to detec any possible
difference related to the topography of the neuron in the
same field. We have found that both CAI and CA3 fields
are correlated in the postnatal development of their
nuclear pyramidal sizes and that al1 topographic levels of
the hippocampus reach their highest karyometric sizes at
the 10th-15th postnatal day. Caudal levels show higher
karyometric values than the other levels and some
differences between neurons of the superficial and deep
layers of both fields are also described here and analysed
in relation to the different ontogenetic gradients of these
cells.
